Strata Drilling Group has the most powerful state-of-the-art limited access equipment on the market. HIGH RESOLUTION VERTICAL PROFILING The Membrane Interface Probe (MIP) is one of the highest resolution vertical profiling tools used to detect contaminations for environmental site assessments and characterizations. MIP is a tool used for mapping Volatile Organic Compounds (VOCs) in soil and groundwater. Using carrier gas, the VOCs are brought to the surface through tubing that is connected to a laboratory grade EC, PID, FID and XSD-detectors for immediate analysis. Laser Induced Fluorescence (LIF) is a Non-Aqueous Phase Liquid (NAPL) mapping tool used to delineate the depth and horizontal extent of free product and residual petroleum contamination. The fluorescence signal scales proportionately with NAPL concentration. Cone Penetration Test (CPT) and Seismic CPT offer cost savings over more traditional boring and sampling methods for the geotechnical industry. Used from a variety of direct push platforms, CPT provides continuous data of the geotechnical engineering properties of soils and delineating soil stratigraphy in situ.

7 GUIDE TO HIGH RESOLUTION VERTICAL PROFILING MEMBRANE INTERFACE PROBE The MIP (Membrane Interface Probe) system is offered by Strata Drilling Group. It is a tool for mapping contaminants in soil and groundwater. The Membrane Interface Probe is a continuous volatile organic compound (VOC) detection system which heats the soil, water, and vapor matrix as it is driven into the subsurface. The VOC mass which is extracted across a permeable membrane is carried to the surface by an inert purge gas via small diameter inert tubing. Once the compounds reach the surface they are analyzed by a suite of three laboratory grade detectors. The sensor detection system includes: Photo Ionization Detector (PID) Flame Ionization Detector (FID) Halogen Capture Detector (XSD) STRATA IMAGING H I G H R E S O L U T I O N V E R T I C A L P R O F I L I N G These three detectors together offer a range of sensitivities and a means of discriminating different classes of compounds anything from chlorinated solvents to gasoline hydrocarbons to methane soil gas. The use of multiple detectors is important for separating different zones of contamination such as petroleum (retail gas station) from chlorinated (dry cleaner). The complementary range of performance of the different detectors enables the system to function from low contaminant level to near NAPL levels. The Membrane Interface Probe is ideal for: Dry cleaners and PCE (Perchloroethylene) sites Manufacturing facilities, warehouses, and other TCE (Trichloroethylene) sites Service stations with BTEX (Benzene, Toulene, Ethylbenzene, and Xylene) plumes Brownfields and redevelopment projects DNAPL (Dense Non Aqueous Phase Liquid) sites Dissolved phase petroleum sites MIP includes an integrated EC (Electrical Conductivity) probe to provide indication of general soil characteristics such as sands, clays, and silts. Using the EC logs you can define zones of lower conductivity which allow the movement of contaminants into the subsurface.

8 GUIDE TO HIGH RESOLUTION VERTICAL PROFILING GUIDE TO HIGH RESOLUTION VERTICAL PROFILING LASER INDUCED FLUORESCENCE CPT & SEISMIC CPT The LIF (Laser Induced Fluorescence) system is offered by Strata Drilling Group to delineate the depth and horizontal extent of free product and residual petroleum contamination. The fiber optic based fluorescence system is deployed with standard direct push equipment. All LIF systems use a laser to send pulses of monochromatic light down a fiber optic line to a probe where the light is emitted and excites any polycyclic aromatic hydrocarbon (PAH) containing compounds in the subsurface, causing them to fluoresce with a characteristic wavelength signature. The induced fluorescence from the PAHs is returned over a separate fiber optic line to the surface where it is quantified using a detector system. The peak wave-length and intensity provide information about the type of petroleum product or potential interferences. The technologies used to investigate petroleum source areas is UVOST (Ultraviolet Optical Screening Tool), a sophisticated system for detecting residual phase SVOCs (gasoline, diesel, kerosene, aviation fuel, machine oils, lubricants, and some crude oils), making it a prime tool for investigating petroleum source areas. The principal difference of UVOST to previous systems is the use of an excimer rather than a solid state laser and the integration of the lasing and detecting systems into a compact, userfriendly package. Use of the excimer and the system integration provides greater reliability, better reproducibility, and less room for operator error. UVOST is ideal for locations such as: Service stations where free product is known or suspected LUST (Leaking Underground Storage Tank) sites Refineries and petroleum terminals Most LNAPL (Light Non Aqueous Phase Liquid) source areas Petroleum DNAPL (Dense Non Aqueous Phase Liquid) source areas Strata Geotechnical provides: Cone Penetration Test (CPT) is performed using an instrumented probe with a conical tip pushed into the soil hydraulically at a constant rate. A CPT instrument reports tip resistance and shear resistance along the cylindrical barrel. Seismic Cone Penetration Tests (SCPT) employs a triaxial seismic digital cone. The cone has a 10 ton (100 MPa) capacity with a tip area of 10 cm2 and a friction sleeve area of 150 cm2. The test collects tip resistance, sleeve friction and pore pressure measurements at a 2 to 5 cm depth interval, which provides a rapid indication of soil behavior. Down the hole seismic shear and compression waves can be measured at 1m depth intervals, as three geophones are embedded in the cone. These values are correlated to a number of geotechnical parameters. FEATURES: Cone Penetration Test (CPT) Cordless probes, providing a constant stream of real-time data while you are probing Information collected: soil resistance on the cone tip, resistance on the outer sides and pore pressure generated during the test Calculates: geotechnical parameters, (SPT) blow counts correlation, shear strength, relative density, friction angle and lateral stress Cone meets the ASTM D-5778 Seismic Cone Penetration Test (SCPT) CPT coupled with Seismic CPT gives details on soil types, engineering parameters and shear wave velocity in the same test hole Cross correlation removes human bias and gives realistic error estimates Seismic cone adaptor is equipped with Geophones so that we achieve the best definition of the frequency spectrum and avoid data smearing Able to measure shear wave velocity and in triaxial configuration for measuring shear and compression wave velocity
